What comes after the ? in an URL is not part of the address but part of the
form data. Sometimes the form data includes whole URLs. I think / is a safe
character, since it is already used in the address part of an URL. Special
characters used in form data can be encoded and decoded for safe
transmission through URLs. I have sometimes seen the / encoded.
